Bring on the Rabbits and Paramecia

At his Bench Marks blog, David Crotty notes that the January issue of CSH Protocols continues its series on emerging model organisms. This month’s picks were the rabbit and the paramecium. The rabbit has been used in in vitro fertilization as well as embryology and organogenesis studies and toxicology and an article from Christoph Viebahn and his colleagues discusses genomic tools for the rabbit, among others. Paramecium tetraurelia is free-living unicellular organism but is distantly related to other unicellular models and Eric Meyer and his colleagues say P. tetraurelia is “ideally suited for genetic analyses.” Previously highlighted organisms include Kalanchoë daigremontiana, yams and the Hawaiian Bobtail Squid.

The Scan

LINE-1 Linked to Premature Aging Conditions

Researchers report in Science Translational Medicine that the accumulation of LINE-1 RNA contributes to premature aging conditions and that symptoms can be improved by targeting them.

Team Presents Cattle Genotype-Tissue Expression Atlas

Using RNA sequences representing thousands of cattle samples, researchers looked at relationships between cattle genotype and tissue expression in Nature Genetics.

Researchers Map Recombination in Khoe-San Population

With whole-genome sequences for dozens of individuals from the Nama population, researchers saw in Genome Biology fine-scale recombination patterns that clustered outside of other populations.

Myotonic Dystrophy Repeat Detected in Family Genome Sequencing Analysis

While sequencing individuals from a multi-generation family, researchers identified a myotonic dystrophy type 2-related short tandem repeat in the European Journal of Human Genetics.
